pps: kc: fix non-tickless system config dependency
CONFIG_NO_HZ currently only sets the default value of dynticks config so if PPS kernel consumer needs periodic timer ticks it should depend on !CONFIG_NO_HZ_COMMON instead of !CONFIG_NO_HZ. Otherwise it is possible to enable it even on tickless system which has CONFIG_NO_HZ not set and CONFIG_NO_HZ_IDLE (or CONFIG_NO_HZ_FULL) set.

This option adds support for direct in-kernel time
synchronization using an external PPS signal.
